Abstract: Cams carried by a power input shaft reciprocate a pair of yokes along perpendicular paths with the ends of each yoke coupled to a pair of oscillating arm members, all carried by a shift ring. Disposed for rectilinear travel between each pair of arm members is a gear plate. Rack gears on the gear plates impart rotation to driven gears of multiple drive assemblies, each of which assemblies includes a driving gear in mesh with an output shaft mounted gear. Rectilinear movement of the gear plates in one direction in response to arm oscillation imparts rotation to the driving gear of each drive assembly while a unidirectional clutch in each drive assembly permits overrunning of the driving gear during return travel of its associated gear plate. Infinite speed changes result from shifting the axes of arm oscillation toward or away from the gear plate ends by positioning of the arm carrying shift ring.

Abstract: An infinite speed transmission having aligned input and output shafts with the input shaft driving a pair of eccentrics each of which oscillates an arm which in turn drives a gear plate housing in a rectilinear manner. Each gear plate housing slidably carries a gear plate equipped with multiple gear racks which drive a pinion gear mounted on the transmission output shaft. Gear plate and pinion engagement for unidirectional rotation of the pinion gear is controlled by a cam which shifts the gear plates within their respective housing. Speed changes are effected by relocating the eccentric driven arms relative the gear plate housings driven by the arms. Repositioning of the cam results in the output shaft mounted pinion being driven in a reverse direction.

Abstract: A rotor of the transmission is journaled within a stationary housing and is driven by rotatable gear rack components therein. A pinion gear drives the gear rack components by sequentially meshing with spaced apart gear racks on each component. A speed selector assembly positions the pinion gear relative the rotor axis and includes a gear train to couple the gear to a power input shaft. Speed changes between the input shaft and a rotor driven output shaft are effected by positioning of the pinion gear away from the rotor axis resulting in the gear rack components moving eccentrically within the rotor. A cam structure acts on each gear rack component to control meshing of the gear racks on the component with the pinion gear. Each of the pairs of gear racks on a modified form of the transmission are resiliently mounted on their respective gear rack assemblies. Rails of each gear rack assembly rotate about stationary but adjustable cam rings of the transmission.

Abstract: An engine including a piston yoke assembly reciprocating within a rotor assembly disposed for rotation within a fixed casing. The rotor assembly is of elliptical configuration to form a pair of exhaust chambers located between the assembly and the casing interior. The rotor assembly defines closed end combustion chambers and fuel-air chamber within which the yoke portion of the piston yoke assembly reciprocates to pressurize fuel-air charges for transfer to the combustion chambers. The piston yoke assembly comprises a part of the rotor assembly but moves about a fixed component carried by the engine casing resulting in reciprocal movement of the piston yoke assembly within the rotor assembly. Power is delivered to the rotor assembly by ignition of a fuel-air charge acting on a piston and yoke assembly off center from the fixed casing component. Exhaust ports within the rotor assembly provide for the ejection of exhaust gases asymmetrical to the rotor axis to impart torque to the rotor.

Abstract: A conveyor for advancing a vehicle along a desired path by means of a wheel contacting pusher assembly. The conveyor base is adapted for placement on an unaltered concrete floor with abutting conveyor base sections, variable in number, being joined at the installation site to provide the necessary length. A continuous chain is confined within upwardly opening guideways with each pusher assembly coupled to a chain component in a manner permitting upward displacement of the pusher assembly about an axis parallel to the chain centerline. Replaceable wear components are associated with the guideways and each pusher assembly. Each assembly includes leading and trailing rollers imparting operational loads to the conveyor base while an intermediate raised roller bears against the vehicle rotating wheel.

Abstract: A car wash apparatus having inner and outer, counterrotating curtain assemblies of circular configuration. Each curtain comprises strip elements which at rest are suspended in close proximity to those strip elements of the other curtain. The strips are displaced during travel over the car body resulting in the strips from one curtain intermingling with strips of the other curtain to enhance the strips cleaning action. A drive mechanism powers the curtains through concentric drive shafts with a water supply shown provided through same. Curtain confining means are supported adjacent the curtain paths guiding the curtain strips for rotational travel into desired impingement against the vehicle body. The strip elements may include highly flexible fibrous segments to clean irregular surface areas of the vehicle. Rotary brushes within the inner curtain assembly clean the vehicle sides. Said brushes are powered via a continuous cable carried by said curtain assembly reeved through power take-off pulleys.
